Accompanying the explosive growth of the Internet have been concerns about protecting children from viewing pornographic and other harmful images through cyberspace. In the past few years, Congress has passed several acts to censor Internet sites available to children, but only the Children's Internet Protection Act (CIPA) has received Supreme Court endorsement to date. In short, public libraries and schools must install filtering software on their computers as a condition of receiving the federal subsidies. CIPA does not specify which filters must be used and stipulates that the filters can be disabled in certain situations for adult patrons. The Supreme Court's endorsement of CIPA, although clearly a victory for groups trying to shield children from cyberspace pornography, does not resolve all the legal issues. Challenges involving the Internet seem destined to increase, and the Supreme Court recently agreed to review a case involving another federal law that imposes penalties on creators or transmitters of indecent Internet materials for commercial purposes if the materials are known to be accessible to minors. The legal questions go beyond concerns about freedom of speech and the protection of minors; there also are significant privacy concerns related to the increasing ease of cyberspace access to personal information about individuals. Undoubtedly, courts will continue to be confronted with complicated legal issues pertaining to sending and receiving transmissions via the Internet, and this is an area of law that school personnel should carefully watch.
